指纹锁

前言

封校生活无聊至极，手上还有个AS608指纹模块没玩过，闲着无聊做了个指纹锁。

一、AS608模块

ATK-AS608 指纹识别模块是 ALIENTEK 推出的一款高性能的光学指纹识别模块。
ATK-AS608 模块采用了国内著名指纹识别芯片公司杭州晟元芯片技术有限公司(Synochip)的 AS608 指纹识别芯片。芯片内置 DSP 运算单元，集成了指纹识别算法，能高效快速采集图像并识别指纹特征。模块配备了串口、USB 通讯接口，用户无需研究复杂的图像处理及指纹识别算法，只需通过简单的串口、USB 按照通讯协议便可控制模块。本模块可应用于各种考勤机、保险箱柜、指纹门禁系统、指纹锁等场合。

切记不可以接5v

识别成功case选择的是0x00可以看到当ensure等于0x00时执行识别成功对应的功能。

总结

一般来说只要是模块类的东西就不难，下一步用人脸识别和指纹一起做一个解锁的。
